Abstract

Multisensory integration is a fundamental form of sensory processing that is involved in many everyday tasks. Those with Attention-Deficit/Hyperactivity Disorder (ADHD) have characteristic alterations to various brain regions that may influence multisensory processing. The overall aim of this work was to assess how adults with ADHD process audiovisual multisensory stimuli during a complex response time task. The paradigm used was a two-alternative forced-choice discrimination task paired with continuous 64-electrode electroencephalography, allowing for the measurement of response time and accuracy to auditory, visual, and audiovisual multisensory conditions. Analysis revealed that those with ADHD ( n = 10) respond faster than neurotypical controls ( n = 12) when presented with auditory, visual, and audiovisual multisensory conditions, while also having race model violation in early response latency quantiles. Adults with ADHD also had more prominent multisensory processing over parietal-occipital brain regions at early post-stimulus latencies, indicating that altered brain structure may have important outcomes for audiovisual multisensory processing. The present study is the first to assess how those with ADHD respond to multisensory conditions during a complex response time task, and demonstrates that adults with ADHD have unique multisensory processing when assessing both behavioral response time measures and neurological measures.

青少年注意缺陷/多动障碍的视听多感觉加工。

多感觉整合是感觉处理的一种基本形式，涉及许多日常任务。那些患有注意力缺陷/多动障碍(ADHD)的人在不同的大脑区域有特征性的改变，可能会影响多感觉处理。这项工作的总体目的是评估ADHD成人如何在复杂的反应时间任务中处理视听多感官刺激。使用的范式是一个双选项强迫选择辨别任务与连续64电极脑电图配对，允许测量听觉、视觉和视听多感官条件下的反应时间和准确性。分析显示，当出现听觉、视觉和视听多感官条件时，ADHD患者(n = 10)的反应速度比神经正常对照组(n = 12)快，同时在早期反应潜伏期分位数中也存在种族模型违反。成人ADHD患者在早期刺激后潜伏期的顶叶-枕叶脑区域也有更突出的多感觉加工，这表明大脑结构的改变可能对视听多感觉加工有重要影响。目前的研究首次评估了ADHD患者在复杂的反应时间任务中对多感觉条件的反应，并证明了ADHD成人在评估行为反应时间和神经测量时具有独特的多感觉处理。

期刊介绍： Multisensory Research is an interdisciplinary archival journal covering all aspects of multisensory processing including the control of action, cognition and attention. Research using any approach to increase our understanding of multisensory perceptual, behavioural, neural and computational mechanisms is encouraged. Empirical, neurophysiological, psychophysical, brain imaging, clinical, developmental, mathematical and computational analyses are welcome. Research will also be considered covering multisensory applications such as sensory substitution, crossmodal methods for delivering sensory information or multisensory approaches to robotics and engineering. Short communications and technical notes that draw attention to new developments will be included, as will reviews and commentaries on current issues. Special issues dealing with specific topics will be announced from time to time. Multisensory Research is a continuation of Seeing and Perceiving, and of Spatial Vision.
